A rules question.

If the piece covering a queen in a battery is pinned due check of the oppenent, why can your king not take the piece that has you in check?

Ummm...... Can you post an example?

The knight is pinned by my rook, why can I not take the queen?

The simplest explanation is this: You may never move your king into check.

So im still moving into check even though the knight is made impotent by the pin? (throws chessboard up against the wall.) Gorram it.

OK. Just think you take the queen. After that the Knight would take your king before you have the chance to take his king with the rook. Since you can't give away your king so you can't take the queen. I hope it's clear now!

Got it muhammed. thanks to both you guys

A check is a check is a check. Whether the checking piece is "impotent" or not, it's still a check.

Happy to help. Bye!

After your king is gone, your controlstation is gone, therefore no more moves can be done.

My friend was wondering if I can checkmate him by leaving my king into check. He had a queen on a5 and played re1 with my queen being on e2 and king being on e6. I played qc2# with my rook being on b2 and his king being on c1. I think that's a legal move.

If your king was still in check, that is an illegal move.

I tried to find rules regarding that situation, but nothing says about checkmate situation.

The rule is: You may not leave your king in check.

This applies after every move.

Thanks for the help.

When you are teaching chess to kids, the easiest way to explain checkmate is in terms of king captures, i.e. when your king has been captured (as will happen the move after a checkmate) you lose the game.  Now, in the sample position you give, KxQ loses because Black plays NxK before White plays RxK - in other words, White's king gets captured first.  Your king only has to live one move longer than your opponent's to win the game.  :)   

Yeah, I got that. A 19 year-old a kid? That's new.
